Wetting front advance and freezing of meltwater within a snow cover: 2. A simulation model

A simulation model is developed which incorporates the effect of flow fingers at the leading edge of the wetting front, ice layer growth within and at the base of the snow cover, and meltwater infiltration into the underlying frozen soils. The model results demonstrated that ice layers grow rapidly over a 24‐ to 36‐hour period due to the conduction of heat into the snow and underlying soil. Sufficient water is frozen as ice layers to slow the …
